1 Claim, 5 Drawing Figures GUN SIGHT BACKGROUND OF THE INVENTION It hasheretofore been the practice in securing or attaching firearm sights bymeans of complementary shaped dove tail slots and tenons, to dimensionthe respective slots and tenons such that it was necessary to forcefullydrive the tenon into the associated dove tail slot by means ofhammering, or through the use of expensive sight mounting presses andthe like. This practice has been objectionable from the standpoint ofthe expenses and time involved in purchasing and utilizing such mountingpresses, but more importantly, from the standpoint that frequently boththe firearm and the gun sight being mounted thereon have been marred,scratched or are otherwise damaged, thus rendering the sights andfirearms aesthetically unattractive and subject to the deleteriousaffects of moisture, dirt, etc.

The present invention is intended to overcome the aforementionedobjectionable characteristics of prior known dove tail mountingarrangements through the provision of a novel gun sight design whereinthe dove tail tenon on the gun sight mounting member is dimensionedslightly undersize with respect to the dove tail slot on the firearminwhich said tenon is to be operatively disposed, whereby the mountingmember may be easily inserted or slid into the slot without any need forhammering the member into place, and without requiring the use ofexpensive sight mounting presses as have been employed in the past. Thegun sight of the present invention is provided with a lockingarrangement whereby after the dove tail tenon has been inserted into themounting slot on the firearm, the mounting member may be convenientlyfixedly secured or locked in place through simple manipulation of ascrewdriverlike tool or the like. Together with rendering the gun sightof the present invention extremely convenient to mount and dismount orremove, the aforementioned arrangement permits extremely simple windageadjustment which, in itself, permits rapid"sighting in and providesmeans cooperable with the associated support means for the sightingelement to provide for a double windage adjustment. Accordingly, the gunsight of the present invention may be rapidly and effortlessly adjusted,and also may be installed in an extremely simply and convenient manner,as hereafter will be described in detail.

SUMMARY OF THE INVENTION This invention relates generally to firearmsights and, more particularly, to a new and improved gun sight whichminimizes to the extreme, the time and effort required for mounting,dismounting and sighting adjustment thereof. Y

It is accordingly a general object of the present invention to provide anew and improved gun sight.

It is a more particular object of the present invention to provide a newand improved gun sight which is extremely simple to mount and convenientto adjust.

It is another object of the present invention to provide a new andimproved gun sight of the above described character which comprisesminimum number of component parts.

It is still another object of the present invention which provides forconvenient interchanging of sight elements so as to provide foruniversality of application.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now in detailto the drawing, a gun sight 10, in accordance with an exemplaryembodiment of the present invention, is shown in operative associationwith a conventional firearm 12. The firearm 12 includes a barrel orreceiver section 14 upon which the gun sight 10 is adapted to be mountedand which is formed with a transversely extending dove tail slot orrecessed area 16, defined by downwardly diverging, transverselyextending forward and rearward surfaces 18 and 20, respectively.Generally speaking, the gun sight 10 of the present invention comprisesan elongated longitudinal extending mounting member, generallydesignated by the numeral 22, which comprises a forward end section 24,an intermediate section 26, and an enlarged thickness rearward section28 adapted for operatively supporting a conventional sighting member orelement 30.

In accordance with the principals of the present invention, the mountingmember 22, and in particular, the forward end section 24 thereof, isformed with a downwardly projecting dove tail shaped tenon, generallydesignated by the numeral 32, which is adapted to be slidably receivedwithin the dove tail slot 16 formed in the firearm 12. The tenon 32 isformed with forward and rearward downwardly diverging, transverselyextending inclined surfaces 34 and 36, respectively, which are of acomplimentary orientation with respect to the surfaces 18 and 20 and aredimensioned such that the tenon 32 may be freely slidably inserted intothe slot 16 without the use of or need for hammering or otherwiseforecefully urging the mounting member 22 into the operative positionillustrated, for example, in FIGS. 1 and 2.

In order to positively fixedly secure or retain the mounting member 22within the dove tailed slot 16 at some preselected transverse positiontherein, the gun sight 10 is provided with a gib locking arrangement,generally designated by the numeral 38. The arrangement 38 comprises alocking screw 40 having an enlarged head section 42 and an externallythreaded shank section 44 which is adapted to extend axially downwardlywithin a suitable countersunk bore 46 that is formed directly rearwardlyof the transversely extending inclined surface 36, as best seen in FIGS.2 and 3. the shank section 44 of the screw 40 extends through the bore46 into threaded engagement with a generally cylindrical shaped wedgeblock or gib element 48 having central threaded bore 50 adapted forreception of the screw 40. The gib element 48 is formed with an inclinedface or facet 52 which is adapted for engagement with the inclinedsurface 20 of the dove tail slot 16. More particularly, when the screw40 is threaded into the gib element 48, the latter is drawn upwardlywithin the lower end of the bore 46, whereby the inclined face 52tightly engages the inclined surface 20, whereby to fixedly secure thedove tail tenon 32 within the dove tail slot 16, once the mountingmember 22 has been located in a preselected transverse position withrespect to the firearm 12.

The sighting member 30 comprises an upwardly projecting, transverselyextending sighting blade section 54 which is formed with a centralsighting notch 56 adapted for sighting alignment with the associatedfront sight (not shown) on the firearm 12. As will be appreciated bythose skilled in the art, the particular size and configuration of thenotch 56 may be designed and selected by the firearm operator so as tobest adapt the firearm 12 for its particular intended use, i.e.,hunting, target shooting, etc. The lower end of the sighting member 30is formed with an integral dove tail tenon 58 which is defined bydownwardly diverging transversely extending inclined surfaces 60 and 62and is adapted for sliding engagement or insertion into a complementarydove tail shaped slot or recessed area 64 formed in the upper surface ofthe rearward end section 28 of the mounting member 22 and defined bydownwardly diverging transversely extending inclined surfaces 66 and 68.

In order to lockingly secure the sighting member 30 at some preselectedadjusted transverse position with respect to the mounting member 22, thegun sight of the present invention is provided with a second gib lockingarrangement, generally designated by the numeral 70. The arrangement 70comprises a locking screw 72 having a head section 74 and an externallythreaded shank section 76 which extends downwardly through and isthreadably engageable with a threaded bore 78 formed in the mountingmember 22 at a position directly forwardly of the dove tail slot 64. Theupper end of the bore 78 is formed with a counterbore 80 within which awedge block or gib element 82 is mounted. the element 82 is formed witha central aperture 84 through which the shank section 76 of the lockingscrew 72 extends, the head section 74 of the screw 72 being nestinglyreceived within a suitable counterbore 86 formed at the upper end of theaperture 84. the gib element 82 is preferably of a generally cylindricalconfiguration and is formed with an inclined face or facet 88 adaptedfor engagement with the inclined surface 60 of the dove tail tenon 58,whereby upon threaded advancement of the locking screw 72 within thebore 78, the gib element 82 may be forced downwardly. whereby the face88 positively engages the surface 60 to rigidly connect the sightingmember 30 at some preselected transverse position with respect to themounting member 22.

In order to provide for elevational adjustment of the sighting member30, the gun sight 10 of the present invention is provided with a screwelement 90 which comprises an externally threaded body 92 adapted forthreaded engagement with a generally vertically arranged internallythreaded bore 94 formed in the rearward section 28 of the mountingmember 22 directly forwardly of the bore 78. the screw element 90 isformed with a lower end section 96 adapted for engagement with an uppersurface 98 of the barrel or receiver section 14, whereupon suitablerotation of the screw element 90 in either a clockwise orcounterclockwise direction will effect raising or lowering of therearward end section 28 of the mounting member 22, and hence will effectraising or lowering of the sighting member 30 until the desiredelevational adjustment is achieved.

In operation of the gun sight 10 of the present invention, it will beseen that elevational adjustments may be made through proper rotation ofthe screw element 90, as above described, and that windage adjustmentmay be achieved through proper loosening or release of the gib lockingarrangement 70, whereby the sighting member 30 may be transverselyadjusted with respect to the mounting member 22, and that the lockingscrew 72 may be subsequently tightened when the desired windageadjustment has been accomplished. It will be noted that a particularfeature of the present invention resides in the fact that windageadjustments may not only be accomplished in the aforesaid manner, butalso by release of the gib locking arrangement 38 and transverseadjustment of the mounting member 22 within the dove tail slot 16 on thefirearm 12. Thus, the present invention provides for a double windageadjustment. It will be appreciated, of course, that at such time as itis desired to remove, replace, or otherwise interchange the sightingmember 30 with a different sighting member having a different shapedsighting notch 56, the locking arrangement may be released in the abovedescribed manner to effect such interchanging. That is, the sightingmember 30, upon loosening the locking screw 72, may be slipped from theslot 64 and another type of sighting member may be inserted in its placeand be secured within the slot 64 upon proper tightening of the lockingscrew 72.

It will be seen from the foregoing that the present invention provides anovel gun sight arrangement which may be mounted and dismounted from afirearm in an extremely rapid and convenient manner, and without theneed for any expensive sight mounting presses, whereby to positivelyassure against marring, scratching or otherwise damaging the sight orthe firearm with which it si associated. As described above, a furtherfeature of the present invention will be seen in the fact that the gunsight 10 is adapted for rapid interchanging of sighting members and maybe rapidly adjusted, boty for elevation and windage corrections. Stillanother feature of the present invention will be seen in the fact thatthe gun sight 10 is of an extremely simple design so that it may beeconomically manufactured and will have a long and effective operationallife.

While it will be apparent that the preferred embodiment illustratedherein is well calculated to fulfill the objects above stated, it willbe appreciated that the present invention is susceptible tomodification, variation and change without departing from the scope ofthe invention.
